To all whom it may concern:

Be it known that I, MARY ELIZABETH FARN- HAM, a citizen of the UnitedStates, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented certain new and useful Improvements in CarStarters; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in a car-starter in whichsprocketwheels are made to operate in conjunction with spur-wheels bymeans of a car-handle, in which a leverage is given to an unusualdegree, and the objects of my improvements are to provide a device thatwill enable a street-car to be readily started without disabling stock,and at same time I furnish a motor that will enable cars to be readilymoved by means of my car-handle. I attain these objects by the mechanismillustrated in'the accompanying drawings, in which Figure 1 is a frontView. View. Fig. 3 is a side view of handle. 4 is a bottom view of cap.Fig. 5 is a top view with cap disengaged.

Similar letters refer to similar parts throughout the several views.

In constructing my device I take a sprocketwheel, as shown by A, andadjust to pipe or rod K. I then place a larger sprocket-wheel, as shownby B, in close proximity to A, and which is held in position byasuitable attachment adjusted to floor of car N, sprocketwheel B beingconnected to A by means of chain C. At D, I place a spur-wheel, whichoperates in connection with E, F being carwheels,G axle of car-wheels, Ha wheel for brake, I a chain, and L a rod, which is placed within K.

M is a cap which is adjusted to end of rod L, the under portion of saidcap having slots or openings, as shown by X in Fig. 4, 0 being a bracewhich supports K, P being a car-handle, Q a pivot on handle, R a screw,and S and '1 are stay pieces or studs on the forward end of a lever, U,which form a connection with openings or slots X and IV, V being abarrel which is adjusted to L.

Fig. 2 is a side Y is a set-screw.

In order to facilitate the adjustment of wheels A, B, D, and E, Iconstruct them in sections. On brace O, which supports K and L, I placea box of Babbitt metal, which can be readily replaced when worn. Thelever U, which is pivoted at Q to the handle P and provided at itsforward end with the studs S and T, is backed by a flat spring, a, sothat when the said lever has been shifted to engage or disengage theslots IV in the barrel V it may be retained in such position by theassistance of the said spring, Z being an ordinary lever, which enablesme to shift my device and which it is unnecessary to explain.

In operating my device I place my handle in position, as shown in Fig.3, and as the car is desired to be propelled forward the driver simplypresses slightly upon the car-handle, when, by means of sprocketwheels AB and spurwheel D,force is imparted to wheel E, which causes wheels F torevolve, thus throwing the car forward and preventing any strain uponthe animals attached to car. Should it be desired to stop the car eitheron an upgrade, level, or a descending grade, driver simply moves handleto the right or left a few inches, when stay-pieces S and T form aconnection with openings or slots 7 and X, which stops the carinstantly, as an instantaneous brake is made by the action ofstay-pieces S and T by a simple turn of handle only two or three inches,and by which with aid of wheel H and chain I a complete check is given acar within a space less than a foot, thereby enabling a driver toabsolutely prevent loss of life of persons who. may be thrown upon thetrack. As heretofore, it would require a driver several minutes to turnthe handle of his carbrake in order to stop his car, and at the sametime require the adjustment of the pawl and ratchet on brake-rod to holdbrake in a positiveposition. This I obviate entirely by my handle andenable a car to be propelled with ease by a slight pressure on my handlewithout even a revolution of the handle.

Having fully described my invention, what I claim, and desire to secureby Letters Patent of the United States, is
